Ecology Homework Help

About Ecology

Ecology is the study of organisms in relation to each other and to where they live. In these questions it means food chains and webs, energy flow, nutrient cycles, population and community, adaptation to habitat, and the human pressures on ecosystems. Data and diagrams feature heavily: pyramids, flow charts and field results to interpret.

Popular topics in Ecology

• Food Chains & Webs

  Producers, consumers and decomposers, trophic levels, and tracing the effect of removing one organism.

• Energy Flow

  Pyramids of numbers, biomass and energy, the ten percent rule, and why chains are short.

• Nutrient Cycles

  The carbon and nitrogen cycles, the role of decomposers and nitrogen-fixing bacteria, and human interference.

• Populations

  Population growth curves, carrying capacity, limiting factors and methods of estimating population size.

• Habitats & Adaptation

  Abiotic and biotic factors, adaptations to aquatic, desert and forest habitats, and ecological niche.

• Species Interactions

  Competition, predation, symbiosis, mutualism and parasitism, with examples of each.

• Ecological Succession

  Pioneer species, seres, climax community, and colonisation of bare ground.

• Conservation

  Biodiversity and its value, deforestation and pollution, and conservation measures and their limits.

How ScanSolve helps with Ecology

ScanSolve reads the food web or pyramid in the image and answers from it, naming the organisms rather than the letters, and traces consequences through the web step by step when a question asks what happens if one species is removed. Energy questions carry the percentage calculation and the reason for the loss.

Where results from fieldwork are given, the answer describes the trend, offers the ecological explanation, and separates the two. Cycle questions are answered as cycles — the process, the organism responsible and the form the nutrient takes at each stage.

Study tips for Ecology

1. 01

   Name the trophic level of every organism you mention. Many ecology marks are for the level, not the organism.

2. 02

   Trace effects through the whole web, not just the next link. "Fewer hawks" usually changes three populations, not one.

3. 03

   For nutrient cycles, learn which organisms do the work at each step. Decomposers and nitrogen-fixing bacteria are the most asked-about.

4. 04

   Give real examples of interactions. A named mutualism beats a defined one every time.
